Separate names with a comma.
Ah - Lobelia erinus, I very nearly cited that as another example of blue!
Too warm, and probably too moist - the seedlings are prone to fungal diseases in these conditions. It really should have been outdoors from the...
Must admit, I'd call those purple, not blue! And ditto for Paulownia. They're not blue like Meconopsis betonicifolia, or some Delphiniums, are...
I've not seen any info on hybrids, but from this paper, it seems Dill (Anethum) and Celery (Apium) are each other's closest relatives, so a hybrid...
No fossils of it. IIRC, the ones produced at the announcement of the species turned out to be less closely related than was thought at first.
The plant in question is definitely Picea abies.
Even with Metasequoia, the local people knew about the species and had planted it on paddy field banks, long before it was 'discovered' in the 1940s.
Yes, that's right; the following 11 genera are currently included in Pinaceae: (subfamily Pinoideae) Pinus - pines (subfamily Piceoideae) Picea...
Yes, Betula utilis subsp. jacquemontii at that location. The dark grey log with scaly bark is something else, perhaps Cedrus deodara or a pine...
Not thorny in the way that a rose is, but IIRC it has twigs that are somewhat spine-tipped, in the same way that Prunus spinosa is. I'll try and...
In a somewhat similar manner, the cone stalks of old Pinus radiata (Monterey Pine) and Pinus muricata (Bishop Pine) cones. Pull a many-years-old...
As an aside, I was including Atlas Cedar in Lebanon Cedar; it is a lot less distinct genetically than Deodar Cedar, so better treated as a...
Depends on how you define 'blunt-tipped', and what you're comparing with. Compared with Picea pungens (Blue Spruce), both P. abies and P. glauca...
Yes, it's still Stranvaesia davidiana; new pic (just above) confirms.
Cedar seeds. Can't tell whether Lebanon Cedar or Deodar Cedar. Several of the seeds are slender and likely empty, unviable, but a couple look...
Definitely Norway Spruce. White Spruce is quite different; shorter, relatively thicker needles, distinctly glaucous (hence 'white'), and normally...
Putting the graft below soil level leaves it at higher risk from soil-borne diseases, so more of the grafts will fail. Also, not all plants will...
Separate forums for me too - ferns are more closely related to seed plants than they are to mosses. The ferns one could reasonably include...
Pics in the first post are Stranvaesia davidiana (syn. Photinia davidiana) - the leaf shape and rather sparse fruit clusters are very typical....
Goats?
