Salvia Amistad - bonkersly big

Hello, 

My Salvia Amistad (probably 5 years old, in its second place in its second garden) is making a bid for world domination - it’s currently over 7 feet tall and 10 feet wide. (The general guidance is that it will be 1.2m high by 1m wide!) I’ve already had to move it once because it was too big. I do love it and don’t want to get rid of it, but it’s totally engulfing and dominating the bed it’s in. Is there any way to stop it getting so ludicrously large?  I had wondered if I should to divide it every other year (which is not something I’ve done yet with any plant - I’m fairly new to gardening) as this would cause it to focus on re-establishing itself and not just growing like it’s on steroids?  Any ideas would be very welcome.  

Thank you. 

Cori

  • I'm afraid I don't have advice (unless pruning?) - hopefully someone will come with some soon - but I'm so curious about your monster salvia 😆 Would you mind sharing a picture?

    Has the soil been enriched, or have you fed and/or watered the salvia? They don't need it! They do absolutely fine here on poor, dry soil and low rainfall. I would think richer soil, feed, more water would all tend to make them grow bigger/more leafy.

    🤣🥳 - That really is a monster!! (The plant - not your hubby!). You clearly have either a mutant plant or absolutely ideal growing conditions.

    I have successfully divided salvia caradonnas many times but don't know about amistad. If you can see division points it I'd probably give it a go.

    Why don't you take some semi-ripe cuttings now (it's getting a bit late but you might be lucky) and perhaps some softwood cuttings in spring as a form of insurance in case the division doesn't work? You could then try dividing the parent plant in spring and see what happens.

    All the best knowledge in gardening seems to come from trying things out - sometimes they work - sometimes they don't. At least if some of the cuttings root you'll have some back up plants to fall back on. 

    If everything works you could set up a market stall....

  • Thanks for your responses.  This bed is newly created, so I dug some compost in then, but other than that the salvia had been ignored and left alone, in fact I felt guilty I wasn’t watering it enough given it was so newly transplanted. It was tall in its previous place, but more constrained so didn’t spread as much.  It’s overwhelming my poor dahlias. 

    Topbird - good idea about taking cuttings now just in case and then trying dividing in the spring, will give it a go.  I have wondered if I had a mutant or even a mislabelled plant, but I can’t find any other variety that grows so big….  And yeah, husband not too bad, will keep.  😄

    Just a couple of months ago I put a Salvia ‘rockin Deep Purple’ in the spot I took this salvia from. It’s sold as a more compact version of Amistad; I shall wait and see how that does…

     I would see it as a bonus. It may be the growing season that it has enjoyed. I would be taking cuttings too. Not sure about division. I did try it years ago one spring, the roots were deep and very woody. It gave up but I had grown it for three years and it cost £1.99p so no problem. It really shouldn't be cut back until spring but maybe you will need to do something to stop it rocking over winter

    Lovely amistad. I would take lots of cuttings.  You may find a hard winter finishes it off.

    I walked past one today, against a wall, must have been at least 10ft. Not very bushy though - quite spindly. Ours is bushier and maybe no more than 3ft but I think it only went in this year.
