Alstroemeria ‘Princess Paola’ – white flowers with pink edges and yellow centres.
The first cut-flower Inca lilies to arrive in South Africa captured the imagination of gardeners and the search was soon on to obtain specimens to plant.
Unfortunately for us, the best long-stemmed varieties were subject to strict breeders’ rights and were kept exclusively for the cut-flower market. As time went by, certain varieties were released to the gardening market and since then, several hybrids have come and gone. Plant cultivators worldwide still take advantage of the fact that alstroemerias hybridize quite easily, and new hybrids are carefully protected by growers.
As pretty as they are, these long-stemmed, cut-flower varieties are almost impossible to keep neat in nursery bags and, because most of us ‘buy with our eyes’, interest in them has waned. In addition, these robust annuals need quite a lot of space, which limits the number of gardeners willing to grow them.
There is a solution though, in the form of several dwarf varieties that have became available. Their blooms make as good a cut flower as those of the longer-stemmed ones and they last just as long in the vase. Even more impressive are the attributes these dwarf alstroemerias bring to the garden. They are easy to cultivate, form compact, dense clumps and never disappoint. They are perfect as filler plants when placed in the foreground of flower beds and they make beautiful pot plants.
When do they bloom?
Flowers are borne from spring through to autumn, when the plants die down and lie dormant through winter (remember to mark their positions so that you don’t accidentally dig them up).
Most suitable climate
Dwarf alstroemerias are semi-hardy and prefer a moderate climate. Gardeners with very cold winters and heavy frost could plant them in pots, but they need to be in a sheltered spot and covered with mulch when they are dormant.
What they need
Location: full sun or light shade, such as morning sun and afternoon shade.
Soil: loamy soil enriched with compost. Add a layer of organic mulch such as compost.
Water: regularly. They prefer cool moist soil that drains well. Fertilizing and pruning: during the growing season feed monthly with water-soluble, potassium-enriched fertilizer. Remove spent flowers by plucking the flower stem firmly from where it emerges from the bulb. This encourages new foliage and flowers. During late autumn, when the plants start to look untidy, trim them back. Renew the mulch before winter arrives.
Watch out for
Snails and slugs love to feast on the soft leaves and flowers, so put out snail bait regularly. Red spider mite may become a pest during summer – inspect your plants often and spray regularly. Light infestations can be washed off with a strong jet of water from your hosepipe.
Get more value
Divide overgrown tussocks during autumn and replant them in well-prepared soil.
