Sunflowers! (Helianthus annuus and H. tuberosus

The volunteer sunflower (H. annuus) is in full bloom, and I'm happy to see it's yellow, not that disappointing brownish orange like the 'Velvet Queen' I had last year (which was supposed to be red).

We also have native perennial sunflowers in the garden, probably Jerusalem artichoke (H. tuberosus). I'm not sure, but I think this is just one plant! It grows over 2 metres tall, and has small (for a sunflower) yellow flowers in the autumn. The roots are massive tubers, which are apparently edible, though I haven't tried it.
