2 plants for large pot

artjakartjak Posts: 4,167

I aquired a large old terracotta pot this week (40 cm wide, 30 cm high - inside measurements). I would like to plant Agapanthus Loch Hope as it is pretty hardy with 2 Heucheras. Will this combination work as far as soil needs? I would mix grit, sharp sand and general compost with a lot of pebbles at the bottom. Any advice very welcome.

    I think I would aim for something to trail over the side to soften it as well - small leaved ivy, helichrsum, which can last, Non of your choice of plants 'spill' out.#Also a qustion but don't heucheras prefer life a little cooller than agapanthus?

  • I'd do for the plain green or, at a stretch, amber heuchera. In my experience, the purples and limes prefer it cooler than your agapanthus will want it. IMHO you'd preobably be better off with one of the small sun-loving hardy geraniums, or even the tough but lovely alchemilla mollis in with the agapanthus. Foliage would give a similar effect and both would flower well before the aga, lengthening your season. The geranium may even stay evergreen, given that you'll have to put the pot somewhere sheltered over winter for the aga anyway... I'd expect the heuchera to start to suffer after a season or two, so unless you want to move the plants into the garden and buy anew each year, they're really not quite right for a hot dry pot...Either of my suggestions would trail a little too, addressing Matty2's point. A different approach would be to plant the aga in a narrower pot, sinking it into the larger with soil around. This would have a double benefit of insulating the aga in the winter and allowing you to put annual bedding around it into the soil at the margin - you could cram it in as you would in a hanging basket without fear of it stealling nutrition/water etc from your aga. You could even tuck some little bulbs such as muscari in deep down in there too (under the bedding) for some spring colour, without the usua worry of it legging it off around the garden ... Just a thought. I've used this approach with smaller clematis to cool their feet and hide their ankles with great success. But if you're set on heuchera, some of the greens with red flowers are real toughies. Bx

    Art I'd have to agree with Matty about conditions for Heuchera and Agapanthus. Heucheras will withstand sun but I never think they look very happy in it unless the soil is moist and fertile so perhaps there's something else which could work better with your Agapanthus. No doubt someone will be able to suggest Heucheras that will be fine! I'd tend to go for soemthing like a Fescue or the black Ophiopogon but it's a question of personal taste. I'm sure you'll get lots of other suggestions too image

    Thank you all so much for the advice; I had not realised that heucharas were shade loving; it means I can move the unhappy one in the flower bed to the 'woodland' area (all of 8sq metres) and I love the convolvulous mauritamica! The pot is going to be in an eye catching position so it needs to be beautiful. Again, thank you all for the time spentimage

  • I was told that agapanthus flower best when a bit congested. In native habitat they grow in crevices, and indeed in my garden they seed readily in my gravel drive where there is absolutely no soil at all. ( lots of lovely free plants)

    However this suggests that they may be best on their own?? I have 2 large blue glazed pots, same size as yours with 7 plants in each. I get 50+ flowers in each later in summer. These are the thinner leaved hardier types and I leave them out all winter but with a bin-liner over them to cut out the rain/waterlogging.

  • I also asked an agapanthus grower at a flower show if they should be congested and he said I am sure your way is good too. Who knows who to listen to, except for our own experience as we try different ways.

    Have to agree with you both about the congestion-I followed that advice and they died! It put me off getting them again but now I'll be tempted to get more and try again. As always it's trial and error isn't it?

    verdun I had a lovely convolvulous with white flowers many years ago which was lovely -foliage was really silvery. Must have been an 'in' plant at the time as I got it in local GC.
