Help with seeds

I planted some plant seeds in a seed tray 3 weeks ago. Nothing has appeared yet. Do you know how long it should be before I see any shoots appearing? (I am a real beginner with this, so please bear with me). The seeds were a gift from someone who visited New Zealand, so they are native plants from over there. They are:Mount Cook Lily (ranunculus lyallii) and Chatham Island Forget-Me-Not Blue (kopukapuka myosotidium hortensia)Hope you can help!



I am not familiar with the plants, so I can only be general. Seeds can take a lot longer than that to germinate. So be patient. The second point is that they may need either some heat OR cold to germinate!! OR they may need light or dark!! Haven't I made it difficult for you! Sorry - but if you can find them in a book or google them, you may find the exact germination needs for these seeds.

Ranunculus lyallii (Mountain Buttercup, Mount Cook Buttercup, or erroneously, "Mount Cook Lily"), is a species of Ranunculus (buttercup), endemic to New Zealand, where it occurs on South Island and Stewart Island at altitudes of 700–1,500 m.[1][2]

It is a herbaceous perennial plant growing to 60–100 cm tall (the largest species of buttercup), with a stout rhizome. The leaves are glossy dark green, peltate, 15–40 cm diameter. The flowers are 5–8 cm diameter, with 10–20 white petals and numerous yellow stamens; flowering is from late spring to early summer.[1][2]

Notable sites for the species include Mount Cook National Park[3] and in other alpine areas of including the area around Arthur's Pass.

Having failed to propagate plants of Mount Cook buttercup from a packet of seeds I bought in New Zealand, I did not give up on my wish to grow this buttercup. The plant growing in my garden came from Blackthorn Nursery in Hampshire, UK. I planted it very carefully incorporating sharp sand, plenty of washed lime-free horticultural grit and peat (to adjust the pH to 5-6) into the planting hole. Taking into account the plant in its native habitat grows in infertile wet sites and is intolerant of high nutrients, I do not mulch or feed my plant excessively but water it regularly from early spring and throughout the growing season. The plant has been growing healthily and vigorously over the past eighteen months and is in flower right now (mid-May). In New Zealand, the garden plants flower between November and January although in the wild they are known to produce scapes (leafless flower stems) as early as October and as late as May.

Dont give up on your seeds too easily, some can take a surprisingly long time. Just when you think they are duds and toss them away they start to germinate in your compost.
