Hypoxidaceae

 

Rhodohypoxis, Hypoxis and Rhodoxis

 

Rhodohypoxis

In 1876 Baker described several species of the genus Hypoxis 'Allmost all of these species are yellow, except the reddish Hypoxis baurii'. After 38 years botanist G.Nel described Rhodohypoxis as a new genus. His main argument was the difference in flower morphology (flower petals standing in two lines), and also the shape and colours of the petals of Rhodohypoxis differ with those of Hypoxis. In the 1920's Mrs. S.K. Garnett-Botfield got some Rhodohypoxis bulbs (rootstocks) from South Africa. These plants did have red and white flowers. She propagated, crossed and selected Rhodohypoxis for years and named some new cultivars. Members of her family did continue her work.

Commercial selling of Rhodohypoxis started in the 1930ties. There are still some of the older cultivars from those days in cultivation. Over the years newly collected Rhodohypoxis have been sent from South Africa to England. And breeding of Rhodohypoxis has and will be continued by several nurseries and plantsmen.

Hypoxis

Hypoxis plants are easily recognized by their bright yellow star-shaped flowers and elongated leaves. Plants overcome winter conditions in the form of a rootstock (corm). This is predominantly a grassland genus, preferring full sunlight. Most of the Hypoxis species grow in the southern part of Africa, but in Asia, Australia and America also some species can be found. Almost all Hypoxis flowers (petals) are yellow, and also pollen grains are yellow. Bees and honeybees do pollinate these flowers. Rootstocks of the larger Hypoxis are uprooted in the hills around villages by African healers. Corms can grow to over 5 cm in diameter. 

At this moment onle a few nurseries have some species in cultivation: Hypoxis parvula, Hypoxis hirsuta, Hypoxis hygrometrica, Hypoxis setosa, Hypoxis hemerocallidae, Hypoxis angustifolia and a few others. There are no cultivars.

Rhodoxis

Rhodoxis (rapid stars) are hybrids from intergeneric crossings of Hypoxis and Rhodohypoxis. A few natural crossings have been send to England to .............    "Rhodoxis hybrida, - Hebron Farm Red Eye and - Hebron Farm Pink".

So far most new plants do have fertile flowers and will grow seeds under the right conditions. So breeding new varieties by inbreeding, crossing and backcrossing should be possible. Seedlings grown do have more variation in plantsize, flower colour and shape of the petals. The yellow colour of the Hypoxis is lost in the first crossing and has not been seen after a first backcrossing.

In England several nurseries have also been breeding new Rhodoxis cultivars.

In 1996 we saw the first flower of a new  Rhodoxis at our nursery. Since then we have been breeding Hypoxidae by crossing Rhodohypoxis, Hypoxis and  Rhodoxis. We prefer natural crossings by various insects, especially hoverflies and bees, flying around at our nursery. Seeds are collected and sown immediatly after collecting. Germination takes 3-6 weeks. Within a year the first flowers of hybrids do bloom. As soon as Rhodoxis flowers open up we take some photo's.  These new  Rhodoxis flowers are shown on our website every year. The best plants are numbered after selection and bulbs are multiplied. After 4-7 years we ask growers to compare new Rhodoxis with the older ones. It takes a minimum of 8-10 years after collecting the seeds before a new Rhodoxis cultivar is introduced.

 So far plants have been grown out of seeds of different crossings:

 

-   Rhodoxis  x  Rhodoxis

-   Rhodoxis Hebron Farm Pink  x  Rhodohypoxis milloides

-   Rhodoxis Hebron Farm Pink  x  Rhodohypoxis milloides Claret

-   Rhodoxis Hebron Farm Pink  x  Rhodohypoxis deflexa

Cultivation of Rhodoxis  

Early in spring pots of Rhodoxis (rapid stars) are repotted in larger pots or divided and repotted in several pots. The soil used is slightly acidic compost with medium sized chicken grit. Pots used for cultivation of Rhodoxis should have a minimum of 1,5 liter. In the first few weeks watering is kept to a minimum. In April when the average temperature rizes pots can be placed outside in full sun. At first new roots and after a few weeks new leaves start to grow. This year after a cold spring flower buds did show in the first half of May. Pots with Rodoxis do need some care during the summer. Every 2 weeks a fertilizer (12-10-18). Dead-heading of spent flowers is necessary. Sometimes pots of  Rhodoxis are filled up in june already. Then one should repot  for the second time. In a larger pot the plant will be flowering and growing better for the summer time.

In August the eye of the flower of Rhodoxis does not like to have water in it for too long. So please shake the flowers if it is raining for days. Plants stop flowering in august/september. Then in november pots should be kept dry, and with first frosty nights pots should be placed on a cool shelf inside a shed. Be aware of mice, they do have an appetite for all corms of Hypoxidae!
