Wurmbea stricta (Wurmbea stricta) is known by a number of botanical names in recent years; previously being called Onixotis triquetra, Onixotis stricta and Dipidax have not given this beautiful bulb any sort of an identity crisis but it means not many people may know exaclty what this beautiful plant is. It’s range of common names is no less confusing; often called South African Water Phlox, Waterflower and even Rice Flower, it is pleasing to say that this plant is much easier to grow than it is to keep up with all of the names it has been known by.
Tall stems hold many attractive pale pink flowers with darker centres, and the tall rush like foliage gives a bit of a hint as to what conditions this gem likes.
Wurmbea will grow in moist boggy soils or shallow garden ponds but they must be kept dry when dormant as they will rot if soil conditions are too wet. Preferring a full sun position, the blooming season is about 3 weeks long and during this time each stem will hold a multitude of delicate looking flowers.

At Garden Express you can make a purchase with confidence. Our living merchandise is normally guaranteed to grow if our free growing guide instructions are followed. Any guaranteed items that do not grow within 3 months (6 months for dormant items) will be replaced, credited to your account or fully refunded.
The exception to this guarantee is discounted, end of season stock which is sold on an ‘as is’ basis. Generally this stock is sound but should be planted as soon as possible and may not perform as well as normal in season products.
Delivery is normally via Australia Post with larger orders delivered via StarTrack Express* courier. We service virtually all areas of Australia with only those areas not serviced by these organisations being excluded (e.g. remote islands and Territories such as Christmas Island, Lord Howe Island, Norfolk Island, Cocos Islands, Groote Eylandt). We do not deliver outside Australia but happily deliver orders placed from overseas for Australian delivery. Our regular delivery charge for basic items is $9.90 Australia-wide, regardless of the number of items ordered. Due to their higher freight costs, bulky or heavy products such as roses, large pots and a small number of hard goods have higher delivery charges. The summary of all current delivery options is:
- Orders NOT containing Roses, 120mm and larger pots/grow-bags, Bare-rooted Trees, Composting Buckets, nor any items with individually specified delivery charges, all delivered at one time, will incur the normal $9.90 freight charge. These items are referred to as “Basic Items”.
- Orders containing bush Roses, 120mm up to 155mm pot/grow-bags, Composting Buckets, together with other products delivered at the same time will incur a $14.90 freight charge.
- Orders containing Trixie Fruit Trees, Dwarf Fruit Trees, Lilac Trees, Standard and/or Patio Roses, 160mm up to a 200mm pot/grow-bags, together with other products delivered at the same time will incur a $22.00 freight charge.
- Orders containing Bare-rooted Trees, Weeping Roses, Magnolias and other Larger items or pots/grow-bags greater than 200mm, together with other products delivered at the same time, will incur a $35.00 freight charge. Remote areas may incur an additional Freight charge but we will notify customers individually if this is the case.
- Orders containing products with explicitly stated delivery charges will incur charges as detailed in the individual product description.
- Some items may delayed due to climatic or growing habits prevent them from being harvested at the time of being offered for purchase. You will be offered a choice to wait until all items on your order are available or to receive what is currently available for an additional freight charge of $4.00.
Orders containing products from two different seasons (eg Rose or spring bulb pre-orders) that require separate deliveries will incur two delivery charges at the relevant rates (unless a free freight offer applies). A $4.00 Quarantine Inspection Surcharge applies in addition to the Delivery Charge for orders delivered to Tasmania, Northern Territory and Western Australia due to the increased complexity of quarantine requirements.
As quarantine inspections apply to each delivery, 2 quarantine charges will apply where orders contain products from different seasons. *Please note that if you order large items (eg Patio, Standard or Weeping Roses, Fruit Trees) you must specify a street address for the delivery address. StarTrack Express generally do not deliver to PO Boxes or RSD addresses so your order will be held until a suitable address is obtained. In rural areas StarTrack may deliver to physical addresses such as general stores that act as Australia Post agencies but we suggest you check with them first. Where ‘Free Delivery’ vouchers apply to an order, details of the voucher should be entered in the “Your message to us” field. Orders (except Pre-orders) are normally despatched within 7-14 working days from the time of ordering during busy periods. Delivery times may be extended during peak periods (typically following the release of the latest catalogue), extended public holidays, if extreme weather conditions are not suitable for live plant transport or as detailed in the product description.
Individual items may be back ordered to avoid delaying the delivery of other items. Please allow additional delivery time for orders to Tasmania, Northern Territory and Western Australia due to quarantine restrictions.
Please note: Some orders may not be possible to parts of Australia due to quarantine and some items may carry unique delivery charges. Check full delivery policy.
General Information: Spring flowering bulbs are usually planted in Autumn, once the heat of Summer has left the soil. In most climates this is any time from April onwards but we recommend waiting until May to begin as this will ensure the soil is cool enough in most areas.
Storing Bulbs Till Planting Time: In order to ensure a beautiful display once spring arrives, please ensure you follow these instructions:
- Store bulbs until planting time in a cool, dry airy position (about 20 degrees and not in the fridge)
- If bulbs are in paper bags, open these to allow an adequate airflow. Bulbs in vented plastic bulbs should have adequate ventilation if left in the bags they have been received in.
- In areas with a mild winter, Tulips and Hyacinths will need to be refrigerated to ensure strong healthy flower stems. Place into the crisper part of the fridge in April, for planting in May- a maximum of 6 weeks in the fridge is adequate; any longer will over chill the bulbs and could cause flower deformities. Ensure bulbs are not anywhere near ripening fruit and vegies during storage or refrigeration.
Planting Width: Varies depending on the species. (refer to measurements in the catalogue.)
Depth: Planting depth for bulbs is very important. Generally speaking most bulbs need to be planted twice as deep as the bulb is high, so the smaller bulbs are planted fairly shallow but the larger ones are planted quite deeply. In pots all bulbs need to be planted no deeper than 2/3 down in the pot so there is adequate room for root development. If planting larger bulbs into pots ensure a deep anough pot is selected to allow for this.
Positioning: Most bulbs Full Sun to Part Shade
Soil: Well Drained soil is essential to prevent bulbs from rotting.
Watering: Spring bulbs are fairly water wise and do not need any extra watering while they are dormant. Once bulbs have begun to emerge from the soil ensure they are kept well watered all through their growing phase.
Fertilising: For best results ensure that the soil is well dug and prepared with organic matter such as well-rotted animal manure, blood and bone or leaf mould. Mulch well to conserve water and keep roots cool. For planting in pots we recommend a potting mix specifically for bulbs. Once bulbs are coming into flower it is important to fertilise again as this will give the bulb enough energy to ensure the flower is set up for the following year.
Lifting and Storage: Most bulbs can be left undisturbed for many years and need to be divided only when the clumps become very crowded. If you wish to lift your bulbs, make sure they are completely dormant and the foliage has browned off before digging. Store in a cool dry area away from vermin if replanting cannot be done immediately.
Why won’t my bulbs flower?
There could be many reasons why.
- Bulbs have not been ‘fed’ in a couple of years (Planting into a well prepared garden bed with a specialized bulb food or general purpose complete fertiliser, and again when flowering to allow plants enough energy to ‘set’ flowers for the next year.)
- Feeding has been with a high-nitrogen fertilizer. (This encourages production of leaves, but at the expense of flowers)
- Bulbs are planted in a shady area. (Most spring flowering bulbs need a half-day of sun at least to produce flowers. Most bulbs will cope with bright shade but not deeply shaded positions.)
- Bulbs are in competition for food and water with other plants. (Planting under evergreen trees or with other fast-growing plants limits the food they can get. Result: weak plants and no flowers.) If this is the case, pay special attention to a regular fertilizer and watering regime.
- Bulbs are planted in an area with poor drainage. Most bulbs love regular watering but must have good drainage. They do not do well where the water puddles. If this is the case, they are weakened by bacterias, fungus or other problems and will rot.
- Plant leaves were cut too soon or tied off the previous year. (All bulbs replenish their bulb for about six-eight weeks after they bloom. The bulbs should be fed at flowering time and kept watered in dry areas for about this long after blooming. The leaves should not be cut off or blocked from sun until they start to lose their green and turn yellow. This signifies the completion of the bulb rebuilding process, and it is then safe to remove foliage or dig up.
- Bulbs may be stressed from transplanting. (Some varieties seem to skip a year of blooming if dug and replanted in a different environment. Some varieties bought in from one climate may have a difficult period of adjustment to a vastly different climate. They may bloom the first year off the previous year’s bulb, but then be unable to adequately build a flower for the following year.
- Growing conditions the previous Spring/ Summer may have been inhospitable – the reformation of the bulb was affected. (An early heat wave may have shut down bulb rebuilding before it was complete. The bulbs may have be grown in a smallish pot without adequate feeding or protection from heat and cold.)
- Bulbs may have been growing in the same spot for many years and need dividing. After a few years of strong growth and multiplication many bulbs need to be divided. Do this by gently digging around the clump once foliage is brown and lifting bulbs out of the ground. Separate and plant about 12-15 cm apart, 2-3 times the depth of the original bulbs. Ensure fertilizer is added to the soil at planting time. Bulbs will probably not flower for another full season after doing this. If your clump is getting quite dense after a few year, pay particular attention to fertilising at flowering time to assist with next year’s flowers.
- Many bulbs require a cool winter to enable them to set adequate roots and grow strong stems. If winter temperatures do not go below 4 C, the bulbs may need to be chilled for 4 weeks before planting. Bulbs in this group are: Tulips, Hyacinths, Crocus and Daffodils.
- In warmer climates it is often usual for many spring flowering bulbs to be treated as annuals (flowers diminish year after year). This is because the weather warms up very quickly and does not allow the plants adequate time to ‘set’ flowers for the following season.
Establish which coloured region you live in and then consider the varieties listed as typically suited to that area. The Australian Climate Guide map is intended as a guide only as climatic conditions vary between specific locations. Factors such as local altitude, wind and the proximity of hills, mountains and bodies of water can cause variations from the generalised climate map. Note also that although a plant may be listed as suitable for a particular region, it may still require protection from extremes such as frost or strong winds. You should also consider its requirements for sun, shade and water.
Remember that you can often extend the range of plants that you can grow by creating micro-climates within your garden. Planting under trees, beside brick walls or in the shelter of a building, on high or low points in the garden can all have an effect. Even planting by a pond or surrounded by rocks can be used to advantage. Part of the joy of gardening can be experimenting and nothing is more pleasing that achieving success with a plant that is not usually seen in your area.
