 Rhododendron 'JG003' |
Origin: Eastern Europe to Western Asia Zone Range: 5-9 Preferred Situation: Semi sun/dappled shade; well draining humus rich soil. Harvest Date: Monday 31 December, 2007
Description: Possibly Rhododendron luteum. Heavily perfumed brilliant yellow flowers appear mid Spring and clothe the entire plant just as the leaves emerge. Highly ornamental. The well established seed plant is only 1.5 meters tall with equal spread.
Notes: This deciduous azalea is part of a rhododendron collection established decades ago by the late Ted and Mary Grieg, renouned plants people who imported from around the world. There is the odd surviving old tin label wrapped around a branch where the faded writing state not a name but an aquisition code. The Griegs found it worthy enough to enjoy in their own garden.
Cultivation: Traditionally propagated by surface sowing under glass and keeping moist, there are always less bulky, alternate ways of starting Rhododendrons from seed. Generally seed doesn't need any pretreatment. Full a 15 cm deep nursery pot with a sterile medium of equal parts of finely milled peat moss, sand, and loam. Sow thinly! Mix seed with a small amount of sand, evenly disperse seed over the surface of the medium (not too much sand as seed need light to germinate) and tamp firm. Direct sunlight will fry seedlings, an artifical light source is best. Keep moist using fine mist as heavy droplets will dislodge delicate seedling roots; use a plastic cover for greater success. Germinate at 20 C and you should see sprouts emerging within 3 months. When at their 3-4 true leaf stage prick out and transplant seedling. Seedlings cannot tolerate winter temps in their first year so its best to place them in a unheated greenhouse or cold frame. Protect seedlings from nibbling varmits. Seed germinates within 3 months.
