Osmanthus Burkwoodii on wall plant list. Native to North America it is a heavy woody shrub to just over a metre high, with glossy green leaves and a long trailing creeping rhizome, widely spreading in the wild. The fruit is edible when heavily powdered and hence this shrub is kept in compacted, wet soil and often suits renaissance style properties. Osmanthus species have been used as forage or as a wood preservative locally, specifically to treat gooseberries and other similar, inedible berries. Its wood has been implicated in treatment of psoriasis and Interstitial Cystitis. A fine annual or short perennial grass, it blooms in summer, reaching its fruiting, heart shaped head in June.
Likely best used in conjunction with a cattle pasture. The small grains of wheat will provide a nutritious food source if done right. Try spreading the runners after the flowers emerge. In doing so, you stop other annual grasses creeping into your seed bed and sharing the pollen. We know they look like they are struggling with the weight of their single huge plant but if we let them develop, they will soon be forced to compete. Daily watering is essential after seeding. Native to Asia and Australia this is a heavy seed bearing grass. Plants reach 2m high and spread by rhizomes. Seedlings are very poorly developed above ground and can take years to reach a good size.
Care of seedlings is quite different to those of our other midlanders. Below ground, the young young start out rooting as simply as possible with the tops remaining attached to the parent plant. The emerging young are left free to wander away from the parent plant to forage or return to the soil where they will develop in the following year. If we are lucky here in Devon we might see a few weeds in our seed bed this year from competition from the weed of choice, weedwithered. Seed produced may last 3 or 4 years in well watered beds. The young seedlings out of water and too much food can take a long time to set seed, usually 2 years, so we advise that it is best not to water seed slowly until after seeding. Seedlings do need regular water with a few spoonfuls of liquid applied at the first sign of growing during the germination season. Apply a solution of 1 part fish tank water to 3 parts water. This will rinse the seed slowly from the soil. Six weeks later a visible seed pod will appear; these get brighter and shallower the further they are from the parent plant.
Osmanthus Burkwoodii of Ilex Crenata
From valley meadows and firesides to rich meadows and coastal lines these plants thrive in north facing just about any grassy surface in the UK. The blooms of Osmanthus are very showy and this is another reason we like this plant so much. Osmanthus formosa is probably the prettiest of the bunch and is probably the one that has been used for many wedding flowers. These perennials are hardy to zone 5 and require neither more nor less water than the other species in our group. If flowered mulch is a must here, sowing early seeds and joining early maturing plants together will also do a lot to improve their chances of success. This species is extremely tolerant of low fertility and needs very little care and attention.
Osmanthus alba is another relatively cold hardy species to keep over the winter. This species does best on drier soil so we would suggest using a good quality white sand for the planting. We’ll be planting seeds in early spring and they will once again survive the winter. If you’re interested in learning more about osmanthus burkwoodii, click here.
A very easy hedge to plant and care for, this plant likes bright direct light but I will go and plant wherever the direct sunlight is.
It is a parasite and attaches itself to almost any other plant, sucking the juices from the inner tissues and leaving behind an incapacitated looking plant with wet ground. blooms from early summer to late summer.
Bracken x oxygastra has it’s pros and cons, the main disadvantage being no real show when it first blooms as the host plant wilts profusely.
The host plant overwinters and looks even better. Until the blooming starts in late summer, you can enjoy the coppery white flowers on show from spring until autumn. New growth reaches its peak in summer and the plants shape-pops late summer to early autumn with a magnificent show of flowers. Blooming can continue well into autumn and we have even seen bees and wasps visiting the trees.
The flowers open quite widely with the disease also known as Oxylucky growing on the individual flowers in a way that looks like small brown spots. The disease only affects the foreground flowers and leaves so f Prospect Park Botanic Garden does recommend against buying any plants with brown spots. If the disease is in your landscape though, this will work as a very effective cover crop, not least because the species presented is not easy to tell apart from regular oxylucky by the colour of the stigmas. See this article for more.
Once the buttercup flower achieves it’s full size and colour the true magic of this species begins, excellent for containers and borders and great for layers in bolder arrangements of your landscape. Use an organic fertiliser as oxylucky only requires the plant matter to have some organic matter in it before the disease sets in which makes this an ideal hedge plant.
Plant seedlings in spring or summer when the weather is warm. Make sure you allow for decent room when planting out to accommodate the higher levels of humidity created by the heat and any drafts from the built up heat. old, weak roots are easy to damage. Will pop up in many habitats including full sun or filtered light, in lower light conditions will require more water but the plants have been known to take off if you overwater them before planting out. Do not water regularly until the plant has established itself. Do not expect it to flower before winter but, in hotter parts of the UK in summer, it can almost double it's bloom time as the blooming period is quite prolonged.
