BEST STRAPPY PLANTS USED AS GROUNDCOVERS FOR SUBTROPICAL QLD – Top 10 (Alphabetical listing)
These are the best pick plants for our TOP 10 Strappy Low Growing Grass-like Plants used as Groundcovers for our local conditions in humid South East Queensland.
We have taken into consideration:
• Proven track record of survival in local conditions over many years
• Low pest and/or disease problems
• Low maintenance
• Looks good!
Dianella caerulea – native flax – though there are many species and cultivars, all have been bundled into this listing. Leaves vary in green colour tone (dark/light tones), width, height, and habit. Small blue-white flowers are produced on inflorescences that tend to stand above the foliage.
Habranthus (H.brachyandrus, H.robustus) – rain lily – this group of bulbous plants are similar in most ways to Zephyranthes, which is why most of the Habranthus species are now reclassified as Zephyranthes. Rain lilies get their name as they tend to flower at the start of the rainy season (summer) after a long dry season (spring). Pink flowers are these plants main appeal though other colours are also available. Grows about 15cm tall.
Liriope ‘Emerald Cascade’ – a truly lovely foliage plant with long semi-curly long deep green pendent leaves making it perfect for use in raised garden beds or pots so the leaves hang down over the edge. Grows about 20-30cm tall, but the leaves will hang down or flop over the surrounding soil. An absolutely stunning landscape feature plant.
Liriope muscari ‘Evergreen Giant’ – a hardy strappy plant that grows 30-40cm tall when mature. Small mauve flowers followed by black-purple berry fruit. Extremely low maintenance which is why it is top pick choice for most landscapers and designers.
Neomarica gracilis – walking iris – not your typical strappy-leaf groundcover but landscapers have used it successfully for this purpose. Fat broad leaves can reach 50cm tall but the walking nature of the plant habit means it can fill an area over time and aesthetically look like a groundcover beneath trees. Each flower only last one day but there are multiple flowers on each flower stalk – a mass planting of this plant is impressive.
Ophiopogon intermedius – plain green parent version of the variegated form. White flowers and blue-purple fruit. About 30cm tall.
Ophiopogon intermedius Alba Variegata ‘Stripey White’ (often sold as Liriope ‘Stripey White’) – as the name implies, it has white variegated leaves which is its main appeal. Grows about 20-30cm tall. Bonus feature are the white flowers and dark blue-purple fruit.
Ophiopogon japonicus – mondo grass – the ever-popular ‘fashion’ plant loved by garden designers in Sydney and Melbourne though it can struggle in the peak of humid summers when grown in South East Queensland. It still is a favourite amongst gardeners and designers due to its low growing habit and dark green leaves that rarely needs any care or maintenance. Grows about 10cm tall.
Ophiopogon japonicus ‘Nana’ – dwarf mondo grass – very slow growing, the dwarf Mondo grass is the ultimate wish-plant for garden designers though the speed of growth lets most people down. Grows about 5cm tall.
Zephyranthes (Z.candida, Z.flavissima) – storm lily, rain lily, storm crocus – a tropical bulbous evergreen plant that have cylindrical leaves. Flowers tend to appear after the storm season starts (Zephyranthes candida with white flowers; Zephyranthes flavissima with yellow flowers; other colours also available). Often planted in rows for a strong architectural linear foliage (and flower) feature. Foliage about 15cm tall.
This list is by now way an exhaustive list of strappy grass-like plants.
Other people may list different species as their top 10, but the plants on this list have been selected by us to ensure success for home gardeners and landscapers who create livable spaces in a subtropical climate.
